Abstract

A contrast-adjustable display via an organic light-emitting device includes a transparent substrate, a light-detectable unit, a current-detectable unit, an organic light-emitting unit, a driving unit and a controlling unit. The light-detectable unit for detecting an external light intensity is formed on the transparent substrate, and then generates a current intensity based on the external light intensity. The current-detectable unit for detecting the current intensity is connected to the light-detectable unit. The organic light-emitting unit is formed on the transparent substrate for generating light. The driving unit connects to and drives the light-detectable unit and organic light-emitting unit, respectively. The controlling unit is connected to the current-detectable unit, and controls the driving unit depending on the current intensity.
